연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A system to stabilize a construction vehicle having a frame and a pair of stabilizing legs with ground-engaging shoes at the ends of the legs. The stabilizing legs pivotally connect to the frame on substantially opposing sides, so that the stabilizing legs pivot upwards to a stowed position and pivot downwards to a stabilizing position where the shoe engages the ground. Further, the stabilizing legs telescope between a retracted position and an extended position. The retracted position locates the shoe closer to the vehicle and the extended position loca...

The system of claim 1 wherein the controller is attached to the construction vehicle, to control the first pair of hydraulic cylinders by extending and retracting one of the first pair of hydraulic cylinders independently of the other of the first set of hydraulic cylinders. 3. The system of claim 1 further comprising: a tractor mounted upon the frame to supply power to move the construction vehicle and to supply power to the first pair of hydraulic cylinders and the second pair of hydraulic cylinders. 4. The system of claim 1 wherein the frame includes a right side and a left side, and wherein one of the pair of stabilizing legs is connected to the right side of the frame, and one of the ground-engaging shoes engages the ground on the right side of the frame. 5. The system of claim 1 further comprising: a loader bucket, pivotally attached to the frame, wherein the loader bucket is adapted to pivot downwardly to engage the ground to assist the pair of stabilizing legs with overcoming the forces of the backhoe bucket scooping and swinging on the stick and boom during excavation. 6. The system of claim 1 further comprising: a tractor mounted upon the frame to supply power to move the construction vehicle and to supply power to the first pair of hydraulic cylinders and the second pair of hydraulic cylinders; anda loader bucket, pivotally attached to the frame, wherein the loader bucket is adapted to pivot downwardly to engage the ground to assist the pair of stabilizing legs with overcoming the forces of the backhoe bucket scooping and swinging on the stick and boom during excavation. 7. A construction vehicle comprising: a system to stabilize the construction vehicle, which has a frame with a tractor mounted on the frame, comprising: a stabilizing leg with a ground-engaging shoe;wherein the stabilizing leg is pivotally connected to the frame, such that the stabilizing leg pivots upwards to a stowed position and pivots downwards to a stabilizing position where the ground-engaging shoe engages the ground;wherein the stabilizing leg telescopes between a retracted position and an extended position, whereby the retracted position locates the ground-engaging shoe closer to the frame and the extended position locates the ground-engaging shoe further from the frame;a hydraulic cylinder connected to the stabilizing leg to power a telescopic movement of the stabilizing leg between the retracted position and the extended position;a second hydraulic cylinder connected to the stabilizing leg to power a pivoting movement of the stabilizing leg between the stowed position and the stabilizing position;a backhoe bucket, mounted on a stick and boom, pivotally attached to the frame, wherein the stabilizing leg is adapted to overcome the forces of the backhoe bucket scooping and swinging on the stick and boom during excavation; anda controller, attached to the construction vehicle, to control the hydraulic cylinder to extend and to retract the ground-engaging shoe,wherein the system is configured to shift the construction vehicle laterally towards the ground-engaging shoe, when the ground-engaging shoe is engaged with the ground, thereby allowing substantially lateral movement of the construction vehicle while the stabilizing leg is in the stabilizing position. 8. The system of claim 7 further comprising: a second controller, attached to the construction vehicle, to control the second hydraulic cylinder to stow and to stabilize the stabilizing leg. 9. The system of claim 7 further comprising: the stabilizing legs is connected to the same side of the frame as the ground-engaging shoe engages the ground. 10. The system of claim 9 further comprising: a loader bucket, pivotally attached to the frame, wherein the loader bucket is adapted to pivot downwardly to engage the ground to assist the stabilizing leg with overcoming the forces of the backhoe bucket scooping and swinging on the stick and boom during excavation. 11.
